MATRIX-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 436,703, dated September 16, 1890.

Application filed April 18, 1890. Serial No. 348,441. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. GooDsoN, a citizen of the Dominion of Canada, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Matrix-Making Machines; and I do hereby declare the following to be a full, clear, and exact descrip- .tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention, though capable of general application, is especially designed for use in connection with matrix-making machines; and it consists in an improvement on the machines described in the several patents issued to me of date November 5, 1889, under Nos. 414,399, 414,400, and 414,637, and my pending application, Serial No. 267 ,7 96, filed March 20, 1888.

The present improvementis primarily directed to the feed for the matrix material, and has for its object to increasethe speed, make I a better matrix, insure the reliability, and add to the durability of the machine.

The character-selecting, the die-aligning, and the die-impressing devices are in this application substantially like those in the former patents and application, and an escapement and stops practically identical with said former application are used for variably limiting the movement of the carriage to effect feed movements of different lengths, as may be required for the selected dies, to produce a matrix differen tiallyspaced, as in newspaper and book print. The feed mechanism and the depressing device are electrically controlled from the character-selecting device. The dies and characters are classified into groups, according to space required, and the feed movements correspond thereto. The diecarrier is in the form of a swinging and sliding lever, having the dies atone end and a hand-key with contact at the other, working over an index-plate with countersunk holes and contacts thereunder. In all of said former machines the feed movement took place in advance of the stroke on the die. This required the parts to be so related as to give the necessary sequence in point of time.

Otherwise the matrix would be destroyed or rendered so imperfect as to be worthless. In other words, the die-stroke had to be Withheld for a sufficient time after the selection of the character to have permitted the matrixcarriage to have moved to its selected limit and stopped. To insure this result it was necessary to avoid connecting up the feed magnets and die-depressing magnet directly in series on the same circuit, and instead some moving part of the feed mechanism was made to close a branch circuit through the die-depressing magnet at the end of the feed movement. The connection being thus indirectly made gave the required sequence, and a circuit-breaker was operated from a movable part of the die-depressing device to break the said branch circuit at the end of the diestroke. This interval between contact at the index-plate and the stroke of the die, to insure the above-described necessary sequence, was much greater than required by the operator to make a contact and to notein his mind deepened to delay him, and would retract the key before the stroke, thus shifting the die from the common center and causing the stroke when given to pound the same against the die-carriage bed-plate, destroying the face of the die. Supplementary circuits on the feed-magnets and other forms of locking devices were added to overcome this last-named evil by holding the key in contact until the completed stroke, all leaving the loss of time unreclaimed, clogging the operator, and introducing objectionable elements peculiar to themselves.

My present invention overcomes all of the above defects and limitations, putting back into the possession of the operator thelost increment of time, leaving no other limitation Whatever to the speed of the machine, save only the quickness of the operators touch in making the contacts and his own mental action in selecting the characters. This is accomplished by the very radical departure of first predetermining the feed movement or setting a limit to the same at the time of selecting the character and making the diestroke and causing the feed to take place after the die-stroke. The matrix material is thus moved while the operator is moving the character-key from one hole to another on the index-plate. The die-depressing device may be run up to a very high degree of speed, and its magnet may be directly connected in a circuit through the contacts at the indexplate, so thatoontact at the key and the diestroke are substantially synchronous. In other words, the selection of the character and the die-stroke are practically simultaneous. The contacts may be then arranged to permit the quickest possible movement of the keyand the key is instantly free after contact. In this construction it should be noted thatwhetherthe matrixmaterialbe first moved the required space for the selected die and the die then impressed, or the die be firstim pressed and the matrix afterward moved the corresponding required space, will make no difference Whatever so far as the relative spacing of the letters in the line is concerned. This change in the feed may be effected in several dilferent ways. I secure the result most simply, as I think, by dividing the feed-carriage into two separable sections, one part being capable of moving ahead of the other and serving as a stop to the other, which holds the material receiving the impression. The former may hereinafter, for convenience, be called the first or advance section and the latter the second or rear section. These advance and following movements of the two sections maybe efiected in any suitable way. I preferably place the entire carriage under tension and provide a detaining device for the second section to withhold it until after the die-stroke. The first section I preferably connect to the escapement mechanism, hereinbefore referred to, for variably limiting its movement and unite the second section to the first by an elastic connection, which will cause it to follow after release from the detaining device.

Referring now to the accompanying drawings, wherein like letters refer to like parts throughout, Figure I is a view partly in longitudinal vertical section and partly in side elevation of a matrix-making machine embodying my invention. Fig. II is a diagrammatic view of the same in plan, some parts being removed. Fig. III is a plan view of the feed-carriage and detaining device detached.

A is the matrix-machine bed; B, the diecarrier.

B is the die-carriage bed; B, the anvil; O, the index-plate with perforations a; G, the contacts thereunder.

DD D D is the die-depressing device, of which D is the frame-work; D, the solenoid; D the constantly-running shaft with eccentric connected to movable core d; D the toggle lever with armature d and plunger d.

E is the cscapment; E, the stops for controlling its throw, of which five are movable and the sixth stationary; e, the escapementreleasing magnet; e e a &c., the stop-controlling magnets and their armatures.

E and F represent, respectively, thepositive and negative binding-posts of a generator. f represents the outgoing wire from same, charging entire bed A, and f the return-wire of same from the detaining device magnet.

1, 2, 3, 4E, and 5 represent branches of the main circuit from the contacts under the index-plate to said stop-controlling magnets, the return portions of which all pass through the escapement-magnet; and 6 represents a similar branch circuit for longest feed directly to escapement-magnet c. All of said branch circuits are normally open at the index-plate.

G G is the sectional or divided feed-carriage, of which G is the first or advance section and G the second or rear section,'which holds the card-board or other material receiving the impression from the dies. These two sections are separable, as stated. The first or advance section G is provided with ratchetteeth engaging with a pinion of escapement E. The two sections are, as shown, connected by springs H. The rear section G has studs or rods h, projecting through holes in the angularly-extended stop-plate g of the front section G and provided with enlarged heads h at their outer extremities. The springs H encircle the studs h between the heads h and the stop-plate g. A weight K is attached by cord K, passing over sheave K to the front section G, placing the whole carriage under tension against the escapement E. Of course a tension-spring might be substituted for Weight K.

To the rear section G is attached a soft-iron bar g, which is extended forward through a groove or opening in the body of the bed made for the purpose to a recess or space A under the forward portion of the bed-plate into the field of an electro-magnet L, and acting as an armature to the same. The armature-bar g is of sufficient length to allow the necessary margin for movements of various lengths without passing outside the field of the magnet L. This armature-bar g and the magnet L constitute a form of detaining device applicable to the second or rear section of the carriage which I deem most simple and best for the purpose.

The magnet L, the solenoid D, the contacts 0, the stop-magnets e, 6 &c., and the escapement-magnet e are all directly connected up in series, on the common circuit f f, having branches 1, 2, 3, 4, 5, and 6. The conductors connecting e, L, and D are represented by wires M and M, respectively, the returnwire f of the main circuit coming from magnet L back to source F. The course of the current is on to the bed, to'the key-lever, to the contacts; thence by the proper branch, according to character selected at indexplate, to the corresponding stop-magnet, to I the escapement-magnet, thence to solenoid-' the die-stroke.

magnet, thence to magnet L, and back to source. It should'be recalled that the shaft D is constantly running at a high rate of speed, and that the divided armature (Z d is capable of practicallyinstantaneous magnetization. V

The operation is evident from the description already given. The instant contact is made at the index-plate. The circuit is closed through magnets L and D and the feed-stop magnet corresponding to the selected die. The armature-bar g is drawn to its magnet L, detaining the rear section G of the carriage, the die is impressed, andthe first or advance section is released from the escapement and is moved by its tension forward to the limit set by the escapement-stop during The forward motion of section G contracts or sets up the springs H, to put tension on the rear section against the detaining device L g. Retractin g the key at index-plate breaks the circuit, setting free the armature-bar g, releasing the rear section G, whereupon it is instantly drawn forward by the springs H to its limit against the stophead 9 of the first or advance section. Meantime the operator may be moving the key to the next desired perforation on the indexplate. The index-plate and the countersunk holes therein are made shallow to give a quick contact. The resulting gain in speed is approximately fifty per cent over my former machines.

In view of the close direct connection of the depressing device with the index-plate contacts and the feed-magnets and the high speed of the constantly-running shaft, contact cannot be made without depressing the die, and as the circuit through the solenoid is broken as soon as contact is broken at the index-plate no stroke can occur after the die has been moved from the common center. Hence there can be no pounding on the dies. The machine is therefore made reliable, the matrix is never mutilated, and the dies will last as long or longer than any other parts of the machine.

In the description heretofore given and in the claims hereinafter made the term carriage has been used, for convenience of definition, to include the feed rack or other equivalent device and the matrix -holder proper, and the term carriage is to be construed throughout this specification and claims to cover any construction whatever comprising two constituent parts, one of which holds the impression material and the other of which is movable in advance the required space to limit the following movement of the other.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

5. The combination, with type-impressing mechanism, of an impression-material carriage composed of advance and following sections and means for moving said sections, whereby the former maybe set forward at the time of selecting the character the space required and made to permit and limit the movement of the other section following after the type-stroke.
